    Measuring State Dependence in Individual Poverty Histories When there Is Feedback to Employment Status and Household Composition

    This paper argues that the assumption of strict exogeneity, which is usually invoked in estimating models of state dependence with unobserved heterogeneity, is violated in the poverty context as important variables determining contemporaneous poverty status, in particular employment status and household composition, are likely to be influenced by past poverty outcomes. Therefore, a model of state dependence ...

    Dynamics of Health and Labor Market Risks

    While there is little doubt that the probability of poor health increases with age, and that less healthy people face a more difficult situation on the labor market, the precise relationship between facing the risks of health deterioration and labor market instability is not well understood. Using 12 years of data from the German Socio-Economic Panel we study the nature of the relationship between ...

    Variable Selection and Oversampling in the Use of Smooth Support Vector Machines for Predicting the Default Risk of Companies

    In the era of Basel II a powerful tool for bankruptcy prognosis is vital for banks. The tool must be precise but also easily adaptable to the bank's objectives regarding the relation of false acceptances (Type I error) and false rejections (Type II error). We explore the suitability of smooth support vector machines (SSVM), and investigate how important factors such as the selection of appropriate ...

    Employer Size, Wages and Unobserved Skills: Evidence from Moonlighters in the UK

    In this paper we examine the labour quality explanation of the employer size-wage gap: larger firms pay higher wages because they employ more skilled workers. Most previous studies control for unobserved skills of workers by applying the fixed-effects estimator to longitudinal data, thus assuming time-invariant unobserved individual heterogeneity. We release this assumption by using a sample of moonlighters; ...

    Tropical Cyclone Losses in the USA and the Impact of Climate Change: A Trend Analysis Based on Data from a New Approach to Adjusting Storm Losses

    Economic losses caused by tropical cyclones have increased dramatically. Historical changes in losses are a result of meteorological factors (changes in the incidence of severe cyclones, whether due to natural climate variability or as a result of human activity) and socio-economic factors (increased prosperity and a greater tendency for people to settle in exposed areas). This paper aims to isolate ...

    Bildungsungleichheiten und blockierte Lernpotenziale: welche Bedeutung hat die Persönlichkeitsstruktur für diesen Zusammenhang?

    This paper examines the impact of underachievement on inequality of educational opportunities. It also investigates whether personality traits are a mediating mechanism between social origin and underachievement. Underachievement is defined as achieving a school attainment that is below the individual cognitive learning potential, measured by tests of fluid intelligence. The paper develops a definition ...

    25 Jahre Sozio-oekonomisches Panel - ein Infrastrukturprojekt der empirischen Sozial- und Wirtschaftsforschung in Deutschland: Einleitung in das Themenheft

    The longitudinal German Socio-Economic Panel (SOEP) study has been providing microdata for social, behavioral, and economic research for over 25 years. This paper presents an overview of this nationally and internationally important infrastructural facility for empirical social research, and shows that SOEP data are of key sociological interest in two respects. First, they allow for annual representative ...

    The Preadult Origins of Post-Materialism: A Longitudinal Sibling Study

    Using a research design that traces siblings' preferences for postmaterialist values in Germany over two decades, this article provides new evidence on the origins of value preferences. Focusing on Inglehart's thesis of value change, the combined socialisation and scarcity hypothesis is tested against the social learning hypothesis - a prominent rival account of preadult value preference formation. ...

    Understanding the Roles and Interactions of International Cooperation on Domestic Climate Policies: Editorial

    Introduction: The United Nations Framework Convention on Climate Change defines the principle of common but differentiated responsibility (Art. 4.1 of UNFCCC). It is the common responsibility of all countries to pursue mitigation actions so as to achieve climate stabilization. The differentiated nature of historic responsibility, capabilities and economic situation creates a responsibility for developed ...

    Policy Targets: Lessons for Effective Implementation of Climate Actions

    Policy targets are used to improve the implementation of domestic and international actions, in a national context and in international frameworks. But how can domestic and international experience be useful for climate policy? Case studies point to the value of defining policy targets more broadly than final outcomes, which in the case of climate policy are CO2 emission reductions. There is a need ...
